CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Japanese Patent Application No. 2011-103382 filed on May 6, 2011. The entire disclosure of Japanese Patent Application No. 2011-103382 is hereby incorporated herein by reference.

BACKGROUND Field of the Invention

The present invention generally relates to a display device. More specifically, the present invention relates to a display device having a pair of speakers.

Recent years have seen dramatic advances in flat-screen television receivers in terms of further reducing the thickness and giving the front cabinet a smaller frame width. This has been accompanied by numerous restrictions on how the speakers are laid out.

A conventional image display component of a flat-screen television receiver has a liquid crystal module, a cabinet that contains this liquid crystal module, and so forth. The cabinet is generally formed by combining a front cabinet and a rear cabinet, The liquid crystal element of the liquid crystal module faces a display window formed by the frame of the front panel. A rearward projection sticks out from the center part of the rear face of the rear cabinet. The board of the liquid crystal module and so forth are housed in the interior thereof. Furthermore, left and right speakers are arranged in left and right symmetry in front view, at the lower part on the inside of the rearward projection of the rear cabinet and at the rear of the liquid crystal module. These speakers are installed in the rear cabinet in an orientation such that they will emit sound downward.

The reasons for arranging the left speaker and the right speaker on the left and right in front view at the lower part on the inside of the rearward projection of the rear cabinet are roughly as follows.

First, to reduce the apparent thickness of the flat-screen television receiver, it is advantageous to make the periphery of the rear cabinet thinner. As a result, it is necessary to form the rearward projection in the center portion of the rear cabinet and house mechanical parts (such as the above-mentioned board) therein. Second, if speakers that can be obtained inexpensively are disposed around the periphery of a rear cabinet that has been made thinner, the size of the speakers becomes a problem in terms of installation space. Third, there are cost limitations on using expensive speakers that are compact and provide high sound quality as the speakers.

In view of this, with the flat-screen television receiver, with the above-mentioned restrictions on speaker installation and price in mind, the spacing between the left and right speakers is set as wide as possible at the lower part inside the rearward projection of the rear cabinet such that the sound outputted from the left and right speakers will be as easy to hear as possible when the user is located in front of the cabinet, and furthermore, the difference in the sound outputted from the left and right speakers will be recognized as clearly as possible when the user is located in front of the cabinet, with the goal being an improved acoustic stereo sensation.

This flat-screen television receiver also has a stand. The image display component with the cabinet, etc., is kept in an upright orientation by this stand. The stand has a flat base that is placed on the floor or a table. The upper face of the base is a flat surface.

Meanwhile, a flat-screen television receiver in which an image display component is supported by a stand has been known (see Japanese Laid-Open Patent Application Publication No. 2010-141610, Japanese Utility Model Registration No. 3,116,087, and Japanese Laid-Open Patent Application Publication No. 2005-165351, for example). Japanese Laid-Open Patent Application Publication No. 2010-141610 proposes a means for improving the stability with which a flat-screen display device is supported by a stand. Japanese Utility Model Registration No. 3,116,087 and Japanese Laid-Open Patent Application Publication No. 2005-165351 propose a means for making it easier to attach and remove the stand to and from the main body. Japanese Laid-Open Patent Application Publication No. 2005-165351 further discloses a constitution in which audio output speakers are disposed facing forward on the left and right sides of a display device (e.g., image display component). Further, Japanese Laid-Open Patent Application Publication No. 2007-86240 proposes a means for preventing a decrease in the aesthetic quality of stand that imparts cushioning in a flat-screen display device.

SUMMARY

However, with the flat-screen television receiver, the left and right speakers are installed facing down and the sound outputted from these speakers is directed downward. It has been discovered that, even though the speakers are installed close to a space that is left under the image display component, the sound pressure toward the front of the image display component ends up being lower, making it more difficult for the sound to spread out forward of the cabinet. Also, even though the spacing between the left and right speakers is set as wide as possible, this spacing is the result of taking into account the many restrictions on the layout of speakers in a flat-screen television receiver. Thus, it is difficult to make the spacing adequately wide. Accordingly, in front of the image display component, the user cannot very clearly distinguish the difference in the sounds outputted by the left and right speakers with the left and right ears. As a result, even though the left speaker and the right speaker are split apart on the left and right when viewed from the front, the acoustic stereo effect produced by the left and right speakers can be considered unsatisfactory.

It has also been discovered that, if the flat upper face of the base of the stand is located under the left and right speakers, then it is also conceivable that a certain acoustic effect will be obtained when the upper face of the base reflects the sound outputted from the speakers. However, the direction in which the sound is reflected by the upper face of the base faces upward from the base. Accordingly, this does not contribute that much to increasing the sound pressure toward the front of the image display component, and sound tends not to spread out toward the front of the image display component. Also, since the spacing between the left and right speakers is not all that wide, the acoustic stereo sensation tends to be unsatisfactory in front of the image display component.

When the technology proposed in the various Patent Literature mentioned above is used for this, it is difficult to increase the sound pressure toward the front of the cabinet of the sound outputted from the left and right speakers installed facing down, or to improve the above-mentioned stereo sensation.

An improved display device was conceived in light of the above-mentioned problem. One object of the present disclosure is to provide a display device with which the sound pressure toward the front of a cabinet is increased, and the acoustic stereo sensation is improved.

In accordance with one aspect of the present disclosure, a display device includes an image display component, first and second speakers, and a stand. The first and second speakers are mounted to the image display component. The first and second speakers are spaced apart from each other in a first direction of the image display component. The stand supports the image display component. The stand includes a base with first and second sound reflecting faces. The first and second sound reflecting faces are arranged relative to each other in the first direction of the image display component. The first and second sound reflecting faces are opposite the first and second speakers in a second direction of the image display component, respectively. The second direction is perpendicular to the first direction. The first sound reflecting face slopes downward as moving away from the second sound reflecting face and forward of the image display component. The second sound reflecting face slopes downward as moving away from the first sound reflecting face and forward of the image display component.

These and other objects, features, aspects and advantages will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment.
